process vs task
Hi,
I am new to this forum and unix too. I have just started learning unix. As I was going through the first chapter, I read that unix is multitasking, multiprogramming, multiprocessing and multiuser OS.
My question is: Is there any difference between a TASK and a PROCESS. How are PROCESS IDENTIFICATION NUMBERS and TASK NUMBERS different?
I searched on google for two days but yet confused..... Please help me.
Thanks in advance

mbk_work_lib
MBK_WORK_LIB(1) MBK ENVIRONMENT VARIABLES MBK_WORK_LIB(1)
NAME
MBK_WORK_LIB - define the mbk working directory
SYNOPSYS
c-shell running
setenv MBK_WORK_LIB unix path
ORIGIN
This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
Paris, France.
Web : http://asim.lip6.fr/recherche/alliance/
E-mail : alliance-users@asim.lip6.fr
DESCRIPTION
MBK_WORK_LIB sets the directory where are saved the results of an invocation of mbk or genlib. This directory is considered to be, from an
mbk point of view, read and write.
Also, when a file is searched for reading, the first directory to be looked at is the MBK_WORK_LIB, and then the one defined in
MBK_CATA_LIB(1).
The unix path argument must be a actually accessible path on your host machine.
ERRORS
"mbk_fopen : can't open file 'unix_path/file.xx'"
This occurs when either the unix path is irrelevent, or when the file doesn't exist if it is open for reading, or when you don't
have the right on the file or directory while trying to write it.
EXAMPLE
setenv MBK_WORK_LIB ~fred/crechan/uom
SEE ALSO
mbk(3), genlib(1), MBK_CATA_LIB(1).
BUG REPORT
This tool is under development at the ASIM department of the LIP6 laboratory.
We need your feedback to improve documentation and tools.
